It can be seen from the name of concrete mixer truck that this kind of mechanical equipment is mainly used for concrete manufacturing and transportation. The mixing transportation of ready mixed concrete is mainly to transport the finished concrete mixed in the concrete mixing plant. During transportation, the rotation speed of the mixing drum must be well controlled at a low speed of about per minute. The blades in the mixing drum are used to continuously turn over and mix the concrete, so as to prevent segregation or hardening caused by static and ensure the quality of concrete transported to the site.

雖然增加了運(yùn)輸距離，可是這種距離和時(shí)間還是不能夠過(guò)長(zhǎng)，不能夠超過(guò)混凝土的凝聚時(shí)間，其時(shí)間還是要受到混凝土的品質(zhì)和環(huán)境等因素的制約。所以嚴(yán)格的說(shuō)不同季節(jié)和時(shí)間下。其運(yùn)輸時(shí)間有所不同。

Although the transportation distance is increased, the distance and time can not be too long, and can not exceed the coagulation time of concrete. The time is still restricted by factors such as concrete quality and environment. So strictly speaking, in different seasons and times. The transportation time is different.

而對(duì)于拌合料的運(yùn)輸與預(yù)拌料則有所不同，拌合料不是成品混凝土，它是一種半成品。所以在運(yùn)輸途中攪拌筒的攪拌速度相對(duì)預(yù)拌料則要快許多，一般情況下根據(jù)混凝土拌合料的配制比例將速度控制在每分鐘八到十轉(zhuǎn)之間。

The transportation of mixture is different from that of ready mixed material. The mixture is not finished concrete, it is a semi-finished product. Therefore, the mixing speed of the mixing drum during transportation is much faster than that of the ready mixed material. Generally, the speed is controlled between 8 and 10 revolutions per minute according to the preparation proportion of the concrete mixture.

為了節(jié)省時(shí)間，對(duì)于拌合料也可以采用在運(yùn)輸途中進(jìn)行攪拌成成品混凝土，這是就需要增加水箱等相應(yīng)的裝置,這種在運(yùn)輸過(guò)程中的攪拌可以增加不少的運(yùn)輸距離，延長(zhǎng)混凝土凝結(jié)的時(shí)間，不乏是一種長(zhǎng)途運(yùn)輸好的選擇。

In order to save time, the mixture can also be mixed into finished concrete during transportation, which requires adding corresponding devices such as water tank. This kind of mixing during transportation can increase the transportation distance and prolong the concrete setting time. It is a good choice for long-distance transportation.

雖然為了增加運(yùn)輸距離和延長(zhǎng)運(yùn)輸時(shí)間，采用拌合料運(yùn)輸途中攪拌成成品料，可以節(jié)約固定投資，提高相對(duì)生產(chǎn)率。但是這種方式的缺點(diǎn)也顯而易見(jiàn)，難以獲得質(zhì)量好的成品混凝土，主要是受設(shè)備的限制不能得到均勻一致的混凝土。

Although in order to increase the transportation distance and prolong the transportation time, mixing the mixture into finished materials during transportation can save fixed investment and improve relative productivity. However, the disadvantages of this method are also obvious. It is difficult to obtain high-quality finished concrete, mainly due to the limitation of equipment.

對(duì)于要求嚴(yán)格的建設(shè)施工來(lái)說(shuō)還是采用預(yù)拌混凝土的攪動(dòng)運(yùn)輸比較好，所以我們大家大多數(shù)見(jiàn)到的都是預(yù)拌混凝土攪拌運(yùn)輸車(chē)。

For the construction with strict requirements, it is better to use the mixing transportation of ready mixed concrete, so most of us see ready mixed concrete mixing trucks.
